The pressure transmitter feels the pressure the electrical element is generally the resistance strain gage, the resistance strain gage is a kind of sensitive device which converts the pressure on the measured piece into an electrical signal. The most used resistance strain gage is metal resistance strain gage and semiconductor strain gage. The metal resistance strain Gage also has the filament strain plate and the metal foil strain film two kinds. Usually, the strain gage is tightly bonded through a special binder to produce a mechanical strain matrix, when the stress of the matrix is changed, the resistance strain Gage also produces the deformation, so that the resistance of the strain gage changes, so that the voltage added to the resistor changes.
